Answer:

The two equations are not equivalent and no property is used.

Step-by-step explanation:

54 - (30 - 8) ... (i)

(54 - 30) - 8 ... (ii)

Solving (i) and applying PEMDAS:

We open the brackets first;

54 - 30 + 8 = 54 + 8 - 30 = 32

Solving (ii) and applying PEMDAS:

We open the brackets first;

54 - 30 = 24

24 - 8 = 16

Sphere A has a radius of 24 centimeters, and sphere B has a diameter of 42 centimeters. The radius of sphere A is multiplied by
Tamiku [17]

Answer:

7/8

Step-by-step explanation:

Sphere A has a radius of 24 centimeters, and sphere B has a diameter of 42 centimeters.

WE need find which factor is multiplied with radius of sphere A to produce the radius of sphere B

Diameter of sphere B is 42

Radius = diameter /2

Radius = 42/2= 21

Radius of sphere B = 21

RAdius of sphere A times x= radius of sphere B

24 * x= 21

Divide by 24 on both sides

x= 21/ 24

divide top and bottom by 3

x= 7/ 8
